Costs of Workplace Productivity Loss in Patients With Fibrotic Interstitial Lung Disease.

BACKGROUND: Fibrotic interstitial lung diseases (ILDs) are highly morbid chronic disorders that frequently occur in working age individuals. The goal of this study was to determine workplace productivity loss, its determinants, and its estimated costs in patients with fibrotic ILD. METHODS: Patients with idiopathic pulmonary fibrosis, chronic hypersensitivity pneumonitis, idiopathic nonspecific interstitial pneumonia, or unclassifiable ILD were identified from the six-center Canadian Registry for Pulmonary Fibrosis (CARE-PF). The Work Productivity and Activity Impairment questionnaire was used to determine health-related productivity loss. Independent predictors of low workplace productivity were identified by using multivariate regression. Patient data were compared with Canadian population census data. The average productivity loss (hours per week) and the individual's hourly wage were used to estimate the costs of productivity loss. RESULTS: Of 650 eligible patients, 148 (23%) were employed. Productivity loss was reported by 55% of employed patients with an average productivity loss of 7.8 ± 0.9 h per week (2.3 ± 0.6 h per week related to absenteeism and 5.5 ± 0.6 h per week related to presenteeism). Employment among patients with ILD aged 25 to 54 years was 23% lower than the age- and sex-matched general Canadian population (60% vs 83%; P < .001). Employment among patients with ILD aged ≥ 55 years was 18% lower than in the age- and sex-matched population (20% vs 38%; P < .001). Dyspnea and cough were independent predictors of workplace productivity loss. Estimated annual costs of productivity loss were 11,610 Canadian dollars per employee with ILD. CONCLUSIONS: Workplace productivity loss is common in fibrotic ILD, strongly correlated with symptom severity, and associated with significant cost.

Workers' compensation for occupational respiratory diseases.

The respiratory system is one of the most important body systems particularly from the viewpoint of occupational medicine because it is the major route of occupational exposure. In 2013, there were significant changes in the specific criteria for the recognition of occupational diseases, which were established by the Enforcement Decree of the Industrial Accident Compensation Insurance Act (IACIA). In this article, the authors deal with the former criteria, implications of the revision, and changes in the specific criteria in Korea by focusing on the 2013 amendment to the IACIA. Before the 2013 amendment to the IACIA, occupational respiratory disease was not a category because the previous criteria were based on specific hazardous agents and their health effects. Workers as well as clinicians were not familiar with the agent-based criteria. To improve these criteria, a system-based structure was added. Through these changes, in the current criteria, 33 types of agents and 11 types of respiratory diseases are listed under diseases of the respiratory system. In the current criteria, there are no concrete guidelines for evaluating work-relatedness, such as estimating the exposure level, latent period, and detailed examination methods. The results of further studies can support the formulation of detailed criteria.

[The pneumonologist and the occupational physician in relation to immuno-allergologic risks in the occupational environment]. / Le pneumologue et le médecin du travail devant le risque immuno-allergologique en milieu professionnel.

The author reviews recent ideas on allergic occupational respiratory disorders which clearly define the severity and the possibility of a cure, thanks to early diagnosis. The diversity of specific and non-specific causes of occupational asthma and the need for research into new causes of pulmonary granulomas are emphasized. The basis for industrial compensation and medico-social prevention are recalled. The author finally looks to the future for a detailed epidemiological study in matters relating to allergic occupational respiratory diseases.
